HPV Hour record attempt by Francesco Russo

Uploaded by: jcgosselin
Video Description:
On August 11th and 12th 2007 on the 3km track of the CERAM Center in France, Francesco Russo tried to break the hour record in his Ristretto, a faired recumbent.
He failed twice due to fog in his fairing and to a puncture.
---------------------------------
Les 11 et 12 août 2007, sur l'anneau de 3 km du CERAM à Mortefontaine, le suisse Francesco Russo a tenté de battre le record de l'heure de Sam Whittingham. A bord du Ristretto qu'il a conçu et réalisé, Francesco était sur de bonnes bases avec une vitesse de croisière de 86 km/h. Hélas, la buée sur sa verrière et des frottements au niveau des pneus conduisant à une crevaison l'ont empêché d'aller au bout.

Hi Frederik!
Yes, Francesco's attempt is serious. He rode 10000 km between October 2007 and April 2008 to get fit for the hour record. He should try again soon.
There was another serious attempt from Damjan Zabovnik on the same track. He started to ride at an average 87.5 km per lap but did not manage to keep the pace. From his experience, the track is faster then Opel test track in Germany, so the CERAM track should be one the fastest HPV track in Europe.
Want to make a try ? ;-)

cool. There was a ... ( 6 months ago by Dallouez)

cool. There was a guy in Motherearth magazine who had a shockabsorber with a gear connected to the sprocket. Everytime he hit a bump the shockabsorber helped move the bike. Some writer wrote about it and tried it out. He was going like a bat out of hell.

We checked. Nobody rode 64.3 miles in the hour. Current record is held by Canadian Sam Whittingham with 86.7 km which is 53.9 mph. 200 m sprint is also held by Sam Whittingham in the Varna with 130.36 kph which is 81 mph.
So I don't know where you eared about a 64.3 mph record...

how hot does it get in the shell? i cant imagine much air circulation inside because of aerodynamics and such

Last July 2008, Francesco rode a complete hour and it was only 24°C inside the fairing at the end. The air was wet and the weather was cloudy.
But it can be very hot inside if the weather is sunny.

Yeah he needs something along the lines of a cycling "time trial" helmet to smooth along that rear tire.

Actually, all the bike is faired. Francesco only rides "top less" to warm up before the attempt.

David Millar is an interesting cyclist but as far as I remember, he has been involved in doping affairs. Too bad as he looked like a clever guy.

So what about the ... ( 3 months ago by MustardMunkey)

So what about the doping? Besides he's most probably being clean for many years now. I am simply saying, "why not get a top pro to give it a go in your machine?" - as they will most likely go much faster than you

There is an air intake at the front of the fairing. Most part of the air goes into a grey tube to the face of Francesco. The other part goes to the canopy to avoid fog formation.
You can see the air intake and the grey tube at 3:37 (you have to pause) of this video.

jcgosselin,
His legs look over-extended to me, at the BDC of the pedal stroke. Is the seat or boom adjustable?

What are you seeing? His legs never fully extend. I think it's his position that might be throwing you off.

See my comment above my first one :-) The camera position threw me off, his leg extension looks fine in later shots.
If his legs did fully extend that would be bad; ideally you want just a tad short of full extension, to prevent strain (and on an upright bike, hip rocking), and to allow power to be developed through the BDC of the pedal stroke.
